Lock 43 - Swift Rapids
Lock 43 is isolated with a sense of wilderness and therefore not practical to drive to by road. This is the deepest single chambered lock on the Waterway. An impressive ground surrounded by lush natural vegetation makes a quiet stop for boater camping and picnicking for the self-contained boater. It is a pack-in pack-out station.

History

Constructed: 1914-1920
As part of the Severn Division, work on the lock, dam and powerhouse commenced in 1914 but was suspended in 1917 due to wartime shortages. A marine railway was built as a “temporary” measure but remained in place until the present lock was built in 1965. At 47 feet (14.3 metres), this lock has the highest lift on the waterway and is a pack-in, pack-out location.
